SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 239,658, dated April 5,1881. Application filed February 26,1881. (Nd model.)

To all whom it may concern:

Be it known that I, JAMES W. HORTON, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Spring Bed-Bottoms, of which the following is adescription.

The object of my invention is a bed-bottom that can be narrowed up andmade to occupy less room for convenience in handling and intransportation.

The invention consists in making the longitudinal slats of the frame sothat they will be held on the end pieces and slide on the same, and inmaking the end pieces in two unequal parts, which are hinged together;so that the longer parts may be folded or turned to a position parallelwith the longitudinal slats, as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a top view of the bed-bottom.Fig. 2 is a view of the under side of the frame, and Fig. 3 is a view ofthe folded frame. Figs. Land 5 are views of the devices for holding theslats to the end pieces.

To enable others to make my improved bedbottom, so that it can bebroughtinto a narrow compass, as contemplated, I will describe it indetail.

The like longitudinal slats c are cut of the 3o requisite length fromflat bars of iron of such size as to give the requisite stifiness. Neartheir ends the caps m are riveted to the slats. The caps are formed fromthin fiat bars of iron, and make, with the slats, the rectangu- 3 5 larslots or spaces a, Fig. 4, when they are riveted to the slats. Holes aremade in the edges of the slats near their ends, by which wire chains areattached to. the slats to keep them on the end pieces and at equaldistances from each other. To the outer movable slat the braces b arepivoted, one end of each brace being bent so as to enter a hole in theend piece to keep the slats distended. The end pieces are cut from flatbars of iron of such size that they will slide freely through the slots91. in the slats, and are made in two unequal parts, 0 and d, theunequal parts being hinged together, as shown in Figs. 2 and 3.

To the ends of the short parts one of the slats is rigidly attached orriveted.

The coiled springs A are the common springs used for bed-bottoms, andare attached to the slats in the usual way. The number of springs onadjoining slats are unequal, and the springs are so arranged that thesprings on the slats having the smaller number will come between thesprings on the slats having the greater number as the slats are movedtogether. The springs are connected together by horizontal wire chains,and, as a consequence of the arrangeme'nt of the springs, all the chainsrun diagonally, except the short chains connectin g the springs on thesame slats.

The thin and narrow top slats, 0 0, Fig. 1, are made of metal, are heldto the springs by loops made of thin sheet metal, which are riveted tothe slats, and are held in position by braces as, which are pivoted tothe slats.

The bed-bottom being constructed as above described, and distended, asshown in Fig. 1, the slats, the braces a and b being turned to aposition parallel with the slats, may be moved onto the shorter parts ofthe end pieces, and the longer parts of the end pieces may be folded orturned parallel with theislats, as shown in Fig. 3.

I am well aware that spring bed-bottoms have been made to be folded, andalso to be rolled together; but

What I claim as my invention, and desire to h secure by Letters Patent,is-

1. A spring bed-bottom composed of springs mounted on slats connected bywire chains, of end pieces made in two unequal parts, hinged together,one of said slats rigidly attached to the shorter parts of the endpieces, and the remainder of said slats adapted to slide on the endpieces, of the horizontal wire chains connecting the springs, of the topslats,

0, and of the braces 11 and w, substantially as shown and set forth.

2. The combination, with the springs A, connected by wire chains, of theendpieces made in two unequal parts, 0 and d, hinged together, and theslats a, connected by wire 5 chains, one of said slats rigidly attachedto the shorter parts of'the end pieces, the rethe end pieces, theremainder of said slats mainder of said slats adapted to slide on theadapted to slide on the end pieces, and of 10 end pieces, substantiallyas set forth. the braces b, substantially as shown and set 3.
